Compatibility report - 98SE on Asus M2V full size ATX with Athlon 64 X2 ---------------------------------------------------------------------------------- It was this thread that led me to get an M2V, so here's my results. You can still find the M2V in Canada but they are gone in USA. The M2V uses a crappy AMI BIOS which allows only 1 floppy and doesn't blank the monitor or turn the drives off in DOS. Have BIOS rev 2001, 1GB DDR2 800 RAM, Athlon 64 X2 4800+ (2.5 GHz) ADO 65W ver #ADO4800DDBOX. Running dual boot 98SE (IE removed with 98Lite) and XP Pro SP2. Both were installed by Ghosting from a drive from an old VIA chipset mbd. For 98SE we used the 'new profile' trick from http://www.motherboard.windowsreinstall.com/win98me.htm It took forever and some blood pressure pills but eventually worked. 98SE cannot use 1GB RAM. In SYSTEM.INI under [386enh] added MaxPhysPage=39000 (tells it to use 998 MB). System shows 898.0MB. Word is you can use anything under 40000. XP chugged and just booted. Installed XP drivers: LPT1 had '!', says 'DMA 04 is being used by DMA controller' (BIOS shows DMA3). Fixed after change in BIOS to 'EPP + ECP' VIA Chipset driver, did both Machine.INF and IDE driver - gave cryptic 'Fail to Installed' but didn't say which! Seems not to matter. Asus PC Probe gave 'ACPI driver install fail - not for this model'. Tried SpeedFan 4.34b26, it worked crudely but in XP only. 98SE: ----- No 98SE driver was ever written as far as I can find for the onboard Realtek ALC660 sound chip or the Attansic L1 NIC. We used cheap add-in cards and disabled onboard ones in BIOS. Got a Sapphire AMD/ATI Radeon X550 128 MB PCIe w/TV, VGA and DVI output for about $40. It has no fan and got quite hot, so we mounted a small ball-bearing fan on its heat sink, 4.8 CFM 5000 RPM. Works like a charm but wipes out the adjacent PCI slot. Catalyst 6.2 works in 98SE. Got it at http://ati.amd.com/support/drivers/98me/radeonaiw-98me.html The 8237A's USB 2 requires drivers for 9x - and none are included. Got VIA driver v2.42L, VIAUSB2V242L.zip. With just the \Win98&ME files on a floppy, Add New Hdw, point to the USB device, not the last two Unknown Devices. Wants USB2VIA.cat, which is absent. Told it Skip, twice. Device Mangler now has 'VIA PCI to USB Enhanced Host Controller'. It works. Programmable Interrupt Controller is VEN_1106&DEV_5351 VIA VT3351 I/O APIC Interrupt Controller (caused sleep problem). Found it in \VIAMACH\VIAMACH.INF (from motherboard CD). Patched VIAMACH.INF by remarking out 'Exclude from Select' line. Now Dev Mgr\Properties\Reinstall Driver works. There are still 2 '?' Devices in Device Manager. One is the SATA in the VIA chipset, DEV_0591. The other shows Resources = Mem FED0 0000+, IRQ 0, IRQ 8. I have no idea what that is, but it doesn't seem to hurt anything. Now both partitions work fine, no problems in XP; with these inconveniences in 98SE: Using only IDE hard drives so far. The front SATA connectors may work in 98SE, the CD has VIA RAID drivers for 98SE - but not tried. Apparantly the 2 rear SATA connectors run by the Marvell 1621 (88SE6121) controller are hopeless in 98SE. Disabled the Marvell in BIOS setup.
